Diverter Valve

  1. Start engine and run at idle. Check diverter vents. Little or no air should flow from vents. Accelerate engine to 2000-3000 RPM and rapidly close throttle. A strong flow of air should pass from diverter vents for 5 seconds.
  2. Slowly accelerate engine. Between 2500 and 3500 RPM air should begin to flow from diverter vents. Replace diverter valve if defective. Valve is not serviceable and must be replaced as an assembly.
